Other than their Root Beer, they don't have anything to offer. Even their coney dog sucks. I think they're better off selling Root Beer at retail outlets or supermarkets.
They were the first fast food outlet in Sg I think. During sec 4 holidays, one of my school mates got the job wearing the A&W bear mascot outfit and stood outside the joint in Katong. Heheh, when we found out it was him, a bunch of us went up to the bear and punched and pushed him till he fell. Too bad we didn't have video phones then, otherwise it'd be on youtube.
Cheers!
